Specilicatiou forming part of Letters Patent No. 47,4834, dated April 25, 1865.

To all whom t may concern: I Be it known that I, EDWARD R. WILRUR, of the city, county, and State of New York, have invented a new and useful Improvement in BottleStoppers, called by me a Coot- Vent;77 and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a View of a longitudinal section of an apparatus for stopping or corking botiles, made and applied according to my invention. Fig. 2 is a perspective view of the mouth of a bottle with Iny stopper applied thereto. y

Similar letters of reference indicate like parts. I

This invention consists of a bottle-stopper which is `made with a passage for air to en! ter the bottle as liquid escapes therefrom, and` which I have called a coot-vent because when liquid is escaping from a bottle or jug, which has no separate inlet-passage for air, the noise made by the regurgitation of the liquid as the pressure of the air overcomes the weight of the escaping liquid reresembles the sound of theword coot.7

A is a bottle to which Ihave in this in stance applied my invention, for the purpose of illustrating it. To the mouth of the bottle I fit a-cork, g, or some other suitable substance, through the center of which I pass a tube, B. The tube and the cork are held to each other by means of circular flanges or caps f, which project from the sides of the tube and inclose the cork between them, the upper iiange being rounded, as seen in the drawings, or it may bemade flat. The bottom of the tube is closed, save that a small hole, d, is made in its edge, and its top, which rises out of the bottle above the cork is open, and when the bottle remains at rest it is covcredby a movable cap, a. The tube B is of different diameters and of irregular shape. The part which is greatest in diameter is mostly contained within the body of the cork, and is divided into two parts, bbz, by thelongitudinal diaphragm b, which is continued'to the top of the tube, and also to its bottom, the part b extending upward a little waysabove the top of the cork, where it opens into i the air, as at h, and also extending downward .into the neck of the bottle where an opening,

. the division'which is` farthest from thefdivi as when the bottle is laidon its side, the `opening c will open upward or be upon ,the

the bottle through division 1 b of the tube B PATENT j OFFICE@ i or NEW YORK, N; Y.

c, is made in its side. The other division or part L2 extends above the cork a considerablel distance beyond the opening` h of the division y b, its mouth being designated by theletter g', The cover a is of such a length asto i close the whole of the tube `above the flang f, thus shutting theopenings g and h of both the divisions. The divisioni .bfterminates at e a little ways below the cork; The later-al1 opening c in division b1 is ou that; side ion b2, so that when division `bzisthelowes highest side of its divisionof theltube.`

The operation of the apparatus is as fol` lows: When the liquid contents ofthe bottle are to be poured, the cap ais removed and the bottle is turned overrwith the division l2 of the tube lowest, when the liquid will enter `it through its inner end, e, and `escape atwits outer end, g. The liquid will not regurgitate during the operation because air will .enter by entering it at h and yescaping therefromat the lateral openingc.. Thus a stream of air is constantly passing into thebottle toll up the place of the escaping liquid. By means of this construction of astopper I overcome the diiiicultyof 1 pouring liquids from a vessel through its mouth or neck,"and prevent loss by spilling, which usually occurs in pouring when no provision is `made for supplying airto the vessel. Thestreamwhich issues from the division b2 is constantand the quantity of liquid to be poured can belthere-` fore better regulated than when it is suffered` to iow with irregularitydandviolence. f

The object of theorice din the bottom of the air-division b is to allow any liquid .which might by accident get in that division to es@ cape intothe bottle. d y This device is applicable to allvesselswhich are emptied ,from `theirjmouths,` as vials, bot` tles, jugs, demijohns, and the like. Itwill therefore bel very useful to apothecaries as well as to householders. ,i` l i `I claim as new and desire to secure by Let-1` ters Patentl y, d
